300 W ATX Power Supply

This 300 W ATX power supply delivers 80 PLUS Gold certified efficiency for systems that prioritise low power draw and quiet operation. It suits office PCs, compact builds and Modern Standby devices that need fast wake times.

Resonant LLC with DC-to-DC conversion

The resonant LLC topology and DC-to-DC conversion provide clean, consistent power while reducing coil whine. A zero RPM fan mode stops the fan entirely at low and medium loads for near-silent running.

Upgrade from lower-efficiency units

Replacing a non-certified or bronze-rated supply cuts consumption, heat and noise at idle and typical loads. The jump is worth it when building or refreshing a system that spends long periods in sleep or light-use states.

この商品に関する質問

Does the 80 PLUS Gold certification mean the unit can exceed 300 W?

No, the 80 PLUS Gold rating only guarantees efficiency levels; the maximum output remains 300 W.

What physical space does this ATX power supply require inside a case?

It uses the standard ATX form factor, so it fits any chassis with an ATX PSU mounting area.

How is the power supply installed, and what step is often missed?

Secure the unit with four screws, connect the 24-pin ATX and CPU power cables, then switch the rear I/O power toggle on.
